How to get CountryName and pass as header to upstream

Help
1

1. caddy:2.4.2-alpine

2. How I run Caddy:

I run caddy as docker container

b. Command:

CMD ["caddy", "run"]

d. My complete Caddyfile or JSON config:

localhost:80, home.so: {     
    route * {
        geoip '/etc/caddy/databases/geo.mmdb'
        reverse_proxy http://192.168.1.101:3000 {
            header_up custom-header test
            header_up Country-Name {geoip_country_name}
        }
    }

}

3. The problem I’m having:

I wanna get the user country name based on their request and pass it to the upstream as a header. i am trying to use this plugin but it does not work, also I saw in the portal that some people said about building geo-ip not sure if this still exists in v2. however, when I use that plugin I get errors. I am most wondering
how can i do this in Caddy v2?
fyi, the path of db is correct

4. Error messages and/or full log output:

Please upgrade to v2.4.5!

Are you sure you mounted or added the database to your Docker container?

How are you building Caddy with the plugin?

Ultimately, this is a question about a third party plugin, the question is best asked on the github repo for that plugin, where the maintainer is more likely to see the question.

Edit: I’m confused, actually. You might have the wrong plugin? See this one:

Thanks for reply @francislavoie

I will update my docker container version, and yes I am pretty sure that my DB file is added to my container. The problem with caddy-maxmind-geolocation is that it only used to filter requests by countries however my problem is to Add country name to the header and send this to backend. The plugin as far as I understand dose not expose any geo placeholder.
